Anyone have any ideas on detecting lightning using a light (or some other) sensor I could hook up to an Arduino?
I have vague ideas of using a photodetector of some sort to trigger some behaviour. It sounds like a hard thing to calibrate.
I know most commercial strike detectors use a radio/magnet detector, but I just need to know when there is a distant flash in an otherwise dim location.
Anyone else done this? I'm probably reinventing the wheel, I know.
Feel free to tell me that my approach is FOS. I'm of to the local 'lectronics shop tomorrow and I'm going to pick up an assortment of stuff that I think might work. Anything I should add to the list?
